Prospecrtive study including 20-30 randomized patients treated by open repair because of an TAAA larger than 55 mm During the surgery, a heart lung machine is applied for distal perfusion during aortic cross clamping to enable distal organ perfusion. Regardless an intensive inflammatory reaction is a well known effect after reperfusion, leading to a uncontrolled inflammation during th first days after surgery. This may be associated to bad outcome and decreased survival rates. By the application of a intraoperative cytokine and DAMP filter this negative ffect could be reduced, resulting in a better outcome after surgery.
